For many years, Eclipta (Eclipta prostrata) was not a problem in rice. As cultural practices and herbicide programs have changed, so has the weed spectrum; it now includes Eclipta more often. Eclipta is a member of the Sunflower family, Asteraceae. Its flowers are numerous in a tight head. The pubescence (hairs) on the stem of Eclipta is antrose, meanining they point from the bottom toward the top which explains why the stem feels rougher when rubbed from the top down than when rubbed from the botton upward.
